This invention relates'to screen separating,

' means, commercially called electric screens,

particularly adapted, for the separation of fluids and semi-fluids, anobj ect of the invention being to provide an'improved; screen separatingmeans which will, have acom;

bined vibrating, voscillating and rotating. motion and thereforesubstantially a uni-f versal' movement so. that every square inchsurface'of the-wire mesh is;agitated thereby preventing the formation ofeddies either in the center of thejscreen or around the peripherythereof. I g '7 'A further object ofr the invention is the provision ofan improved screen separating 'mea-ns which can be readily vattachedtore ceptacles -of different diameters or of different shapes and inwhichscreen separating pans of different sizes or of a dilferentwiremesh can be readily interchanged, and which will be simple inconstruction, eficient in ope.

eration; and extremely fieXible for mounting V on varying shapes andsizes of tanks aswell' as for the substitution of pans, of differentmesh" or of different size. I v

since the invention is capable of other 'em-' bodiments, and that thephraseology which we'employ is for the purpose of" description I i i andnot 'of1limitation.

the preferred form thereof shown comprises 'a-screen pan 2 consisting ofa rim 3 curved inwardly at its top,as at 4, to direct the fluid towardthe; interior of the pan and prevent splashing. thereover. The bottom'of this pan-is formed of'asuitablewirelnesh or wire] cloth: '5.-Enc1rcl1r 1g the pan ,is. a two-part "clainpingband- Gadjustablefto fitdifferent sizes or pans, the two parts being hinged as at 7 This band{engages the pan under a This improved screen separating means' in v ping band has one end fprovidedfwith a-pair of lugs or ears 8 and 9 forthe reception of a'threaded rod '10 forming the other part of the band,.theoppoSite end of which is hingedto the band part 6.". This rod iscurvedjto conform to the shapeofathe pan and 'th'eje nd' of this rod hasa thumb nut 11 and: a check.;nut 12 whereby the clamping 7 device maybeadjusted; tofit varying sizes of pans. At the hinged connectioni of theband is located am lever clamping device 13. for insuring a; tightfitting of the band to 1Q isprovidedfat its end with a curved memberorcam arm 14 t owhichis pivoteda hand lever 15,}the inner end of whichis pivotally can be readily removed'and replaced. This clamping band isconnected; with a'rectan 7 gular supporting frame 17 by a pair ofantifriction bearings 18,. one at each side and diametrically opposedandfor thispurpose V ing bearing means theianti frict'ion bearings the pan,and for this purpose the curved rod 1 connected between a pair of lugsor ears 16 'on the other member of the band so that bythrowing the leverin one direction as-in a deadcenter positionor away from the pan, Itheiclan pingband will be securely fastened ,or released from the pan sothatjthe'pan or balls 21 are located. The rectangular frame 17 isprovided with a plurality, shown as four in number, of swiveledsliding-clamps 22 for attachment to the receptacle. Each of of theseclamps 22 comprisis a U-shaped or forked member 23 carrying athumb-screw or bolt 24: for clamping it to the rim of the receptacle ortank. This forked member is providedcwith a spindle or bolt 25 carryinga pair, of clamping members 26 for'the reception of'the rectangularframe 17, and the top of the bolt 25 is provided with a thumb-nut 27whereby the clamping members 26 can be tightly clamped to therectangular frame.

Bythis sliding and swiveled clamping means it will be observed that thescreen separating pan may be readily attached to the top of a tank ofvarying sizes and shapes.

The ends of the rectangular frame 17 are connected by a bolt orreinforcing rod 28. For imparting vibratory movement to the separatingpan the clamping band 6 is provided with a rearwardly extending'crank'arm 29 having a bore 30 iitting an eccentrically formed hub31 of a bevelgear 32 loosely mounted upon a spindle 33 carried by a motor base'orplate 34. This gear32 is in mesh with abevel gear 35 carried by theshaft of a suitable small motor 36 mounted on the motor baseor plate 34,and this motor base or slate is rigidly secured to the rectangular frame17 whereby the whole mechanism can be readily and quickly detached andreplaced as a unit. The bevel gear 82 is counter-weighted to neutralizeits vibration andthis counter-balancing is obtained in the presentinstance by forming the gear with recesses or openings 37 and thenfilling in one-of these recesses with lead as at 38.

From the foregoing it will be observed that the screen separating pan issupported by only two anti-friction bearings oppositely located and thatby-reason of the eccentric connection between the bevel gear 32 and thecrane arm 29, the pan is given a'forward and backward movement and asidewise movement in a rotary path so that there is substantially auniversal movement of the pan with the result that every square inch ofsurface of the wire mesh is agitated, thus preventing the formation ofeddies either in the center of the screen or around the peripherythereof. It will also be seen that the pan maybe readily supported ontanks, not only of different sizes or diameters, but on round or squaretanks, since the swiveled clamps secured to the rectangular frame may beslid along the same to any desired position and by means of theadjustable clamping band various sizes of pans may be interchanged andtightly clamped in position for shiftable movement by the motor drivengearing, so that the construction of this separating means is simple indesign, efficient in operation and flexible for mounting it on tanks ofvarying shapes and sizes and for the interchanging of screen pans of(lifeferent sizes or having different wire mesh.

In practice, the driving mechanism may be suitably enclosed by a coveror casing 39, thus providing a very simple, easily handled screenseparating means;
